摘要：

High-resolution interferometry using far-infrared laser radiation is employed on TEXT-Upgrade to measure the spatial and temporal evolution of the electron density profile as well as small-scale perturbations. Perturbations to the electron density induced by naturally occurring sawtooth oscillations or externally imposed gas modulations can be used to ascertain the local particle flux and transport coefficients in the plasma interior. Density islands associated with Mirnov activity can also be resolved, providing detailed information on the density profile at island X and O points. Implementation of a second orthogonal view will allow accurate determination of the density profile in the various asymmetric plasma configurations of TEXT-Upgrade.
